GENERAL DESCRIPTION

The ADM1170 is a hot swap controller that safely enables a printed circuit board to be removed and inserted to a live backplane. This is achieved using an external N-channel power MOSFET with a current control loop that monitors the load current through a sense resistor. An internal charge pump is used to enhance the gate of the N-channel FET. When an overcurrent condition is detected, the gate voltage of the FET is reduced to limit the current flowing through the sense resistor.
